It's mostly Gmail messages that are being affected, but not entirely.
A recent non-Gmail message that was duplicated was sent by mokoNinja
<ninjutsu at openmoko.org> on 8/16 with:
Subject: "Re: Fingerscroll, foofone and more from people.openmoko.org!"
Message-id: <C9519FF2-9BA7-40AB-BA0E-3D00CD3AA8A6 at openmoko.org>
There have been others in the past too; I've noticed them from
starband.net, cnlohr.com, and axialys.net. If you want more details,
see the messages I've sent to this list such as "Duplicate message
troubleshooting" on 7/24.

The RFC says: "In general, the retry interval SHOULD be at least 30
minutes; however, more sophisticated and variable strategies will be
beneficial when the SMTP client can determine the reason for
non-delivery." (Source: http://www.faqs.org/rfcs/rfc2821.html section
When I look at the messages I've seen duplicated from Gmail, the first
retry is usually after 8-10 minutes but then it backs off to about
20-30 minutes for a message or two, then 1 hour or longer for the
rest. Maybe they're trying a "more sophisticated and variable"
